The use of propofol (2,6-di-isopropofol) for sedation during endoscopic procedures has increased in recent years primarily because of its favorable pharmacokinetic profile compared with traditional endoscopic sedation with benzodiazepines and opioids. Propofol has a rapid onset of action (30-45 sec) and short duration of effect (4-8 min). There also are data to support the safe use of propofol for advanced endoscopic procedures such as endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS).
